Ponding collapse analyses of light weight roof structures by water raising capacity

[摘要] Local collapse of flat light weight roof structures due to ponding frequently occurs in the Netherlands. In the article the circumstances under which ponding occurs, are described. The term "water raising capacity" is introduced and defined as highest water level that can be achieved on the structure. This water raising capacity is used for explaining local collapses due to ponding by analyses and for design to prevent structures to collapse due to ponding.
